The vehicle repeatedly displays a "Stop Vehicle and Check Brake System" warning together with an ABS warning, accompanied by a loss of normal braking response. On XXX, while driving at approximately 60 mph on I-85 northbound near Exit XXX in [XXX], the warnings appeared and the brakes did not respond normally. I was maintaining a substantial following distance, and the braking system restored itself before I reached the point of needing to brake hard, so no crash or injury occurred. Had hard braking been required in that window, I do not believe the vehicle would have stopped as commanded. This is a recurring fault. The vehicle, purchased certified pre-owned and still under the Hyundai factory warranty, has been taken to the dealer (Ed Voyles Hyundai, [XXX]) three times for the same condition. On the first visit the Integrated Electronic Brake (IEB) unit was replaced; on the second, the Smart Junction Box was replaced; on the third, the dealer removed an aftermarket tracking device wired to the data link connector and referenced Hyundai TSB 24-GI-011H, representing the problem as corrected. The braking-loss event on XXX occurred after that repair. The vehicle has been out of service approximately 30 days total. Because the failure is an intermittent loss of braking response at highway speed, I consider it a serious safety hazard and no longer drive the vehicle.

Steering, suspension & tires

Most reports here involve loss of steering.

The ioniq 5 highway driving assist, which steers the car and keeps it centered in the lane, will disengage without clear warning - the small green steering wheel icon (which is at the top of the dash cluster) simply becomes grey and blinks, but there's no audible chime to indicate that the car has disengaged the steering assist. I have had multiple times on the highway where it disengaged and I don't notice (because I am looking at the road, not the dash) and one time on the highway it disengaged during a turn and hit the rumble strip, causing me to swerve back onto the road. My hands were on the steering wheel and I was paying full attention, but I was expecting the car to handle the turn, and it just disengaged without me noticing. Had there been another car in the middle lane or I reacted slower, it's likely a crash would have occurred. This has been documented as well on Reddit and confirmed by multiple owners, who have mentioned they have disclosed to the manufacturer: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a yellow air bag (SRS) safety restraint critical wire harness underneath the seats and it's loose and hanging down touching the floor with lots of slack, very easy for a water bottle or any object to roll under there and pull it loose, which would disable a critical passenger safety system. This issue is reported by many drivers including myself, photos attached are from multiple people's experiences with this issue.

Rear hatch window spontaneously shattered for no apparent reason. Car was parked in a Florida parking lot, no use of rear hatch and no use of rear defroster. I understand there is a potential class action lawsuit for the Ioniq 5 model years 2022-2025 for this problem.
